Abstract
Official abstract text for this publication.
Systems and methods for controlling permeability in vacuum infusion processes are disclosed. A system includes a tool surface, a flexible film, a preform, a magnetic field source, and a magnetic element. The flexible film has a periphery sealingly coupled to the tool surface to define a volume. The preform is disposed within the volume. The magnetic field source is configured to generate a magnetic field. The magnetic element is positioned to receive the magnetic field generate by the magnetic field source. The magnetic element is configured to move the flexible film away from the upper side of the tool surface under application of the magnetic field. A method includes generating a magnetic field with the magnetic field source and receiving the magnetic field with the magnetic element to move the flexible film away from the upper side of the tool surface, thereby increasing permeability of the preform.
First claim
Opening claim text (preview).
What is claimed: 1. A method for controlling permeability in a vacuum infusion process comprising: sealing a periphery of a flexible film to a tool surface to define a volume between a lower side of the flexible film and an upper side of the tool surface; disposing a preform within the volume; providing a plurality of magnetic elements, each of the plurality of magnetic elements configured to move a portion of the flexible film away from the upper side of the tool surface unde…
